Excessive noise, suspected drug and alcohol use

The owners of this house comes home at about 2:00am to 2:30am on a regular basis. They blast their music at full volume during these times, or from his house. Other times the male of the house will yell at people who are in his driveway. A lot of times, women have also been heard screaming and laughing loudly. His guests also hoot and make a lot of noise when leaving the house. It is suspected that the owners are either drunk a lot of times, on drugs (seeing as this neighbourhood has been a drug exchange hot-spot), or just inconsiderate. Research shows that legal action can be taken against excessive noise. The owners of houses around this man's house also has issues with his loud music and strange behaviour. We tried to talk to the man, but he went berserk and threatened us.
